CLEANING-FLUIDJNTRODUCING- MEANS FOR ENGINE-CTLINDEBS Specification ofLetters Patent.

Application filed April 11, 1917. Serial Ho. 161,348.

T0 all whom it may concern:

Be it known that I, ARTHUR THOMPSON, a citizen of the United States,and'a resident of Toledo, in the county of Lucas and State of Ohio, haveinvented a certain new and useful Cleaning-Fluid-Introducing Means forEngine-Cylinders; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompan ing drawings, and to thecharacters 0 reference marked thereon, which form a part of thisspecification.

This invention relates to means for clean ing and removing carbon fromthe cylinders of internal combustion engines.

The primary object of my invention is theprovision of a simple devicefor containing a carbon cutting or softening liquid, such, for instance,as kerosene, and adapted to be easily and quickly attached to thepriming cock of an engine cylinder in valve-controlled communicationwith its interior, whereby a quantity of such liquid is drawn into thecylinder at each suction stroke of its piston.

The invention is fully described in the following specification, andWhile, in its broader aspect, it is capable of embodiment in numerousforms, a preferred embodiment thereof is illustrated in the accompanyingdrawings, in which,--v

Figure 1 is a side elevation of a device embodying my invention inoperative connection with an engine cylinder and having portions brokenaway. Fig. 2 is a perspective view of the priming cock engagmg nippleand the means associated therewith for releasably connecting it to thepriming cock, and Fig. 3 is a difierent perspective view of a portion ofsaid. connectmg means. i

The

adapted to fit into the cup 3 of the priming cock 2. A collar 9 ismounted for longitudinal adjustment on the reduced outer end portion ofthe nipple 8, being secured in adjusted position thereto by a set screw10 and having its outer side faced with a gasket 11 to form a close,liquid-tight fit against the rim of the cup 3, as shown. The nipplepassage is enlarged at the rear of its discharge end to receive a checkvalve 12, in the present instance, of the ball type, which seatsagainstthe inner end of such enlargement to normally close the passagetherethrough, and is yieldingly held seated by a spring 13. A. latchmember 14.- ispivotally connected to the nipple 8 for trans-.

verse swinging movements relative thereto and is adapted to swing intoand out of engagement with the neck portion 4 ofthe priming cock '2,being provided with a notch 15 in one end of its bottom portion forreceiving said neck. When the nipple 8 has been placed with its outerend projecting into the cup 3 and with its stop-shoulder or collar 9resting on the rim of said cup, the catch member 14 is then swung fromthe dotted line position shown in Fig. 1 to the full line position, inwhich latter position the catch member engages under the bottom edge ofthe cup 3 and draws the shoulder 9 closely to the cup rim. The catchmember 14, in the present instance, has a finger piece Referring to thedravings, 1 designatesg'lhe "yoke 18 has an opening 19 therein an enginecylinder an piming cock attached thereto, said cock.

2 the customary through which the outer end of the drain cock 6.projects and is intended to be firmly clamped to a shoulder or nut 20 onsaid drain cock by the nipple 8.

The cylinder 5 has its outer end provided with a removable cap orclosure member 21 to facilitate a fii'ling of the cylinder.

It has heretofore been the practice, in introducing kerosene or othercarbon softening and cleaning liquid into the cylinders of an internalcombustion engine, to introduce such kerosene through the carbureterously into all of the cylinders causes a choking and frequent stoppingof the engine, while the principal objection to the latter method isthat the liquid cannot be intro: duced when the engine is running. Withthe use of my device it makes no diiference how fast a cleaning liquidis drawn into a cylinder with which connected, as the explosions takingplace in the remaining cylin ders of the engine will cause a continuousrapid running of the engine, so that there is no danger of choking theengine. It is also found in practice that a more effective cleaning ofan engine cylinder can be accomplished by the use of my device than byeither of the methods above referred to or by any other method of whichI am aware.

I wish it understood that my invention is 'not limited to any specificconstruction, ar-

rangement or form of the parts, as it is capable of numerousmodifications Without departing from the spirit of the claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is-

l. The combination with the cylinder of an internal combustion engineand a prim: ing cock attached thereto, said cock having a cup at itsouter end, of a receptacle for a cleaning liquid having a drainagenipple adapted to reniovably seat on said cup, an outwardly openingoheckvalve disposed in said nipple, and meanscarried by the nipple andoperable to releasably engage the priming cock to retain the nippleinclose engagement therewith. y a

2. The combination withthe cylinder of an internal combustion engine andapriming cock therefor, saiii cock having a cup at its outer end, of areceptacle for containing a cleaning liquid, a drainage cock extendingfrom thelower end of said receptacle and having a nipple at its outerend for 1 seating in the cup of said priming cock, an outwardly openingcheck valve in said nippie, and a catch member pivotally connected tosaid nipple and adapted to swing into holding engagement with the underside of the priming cock cup to retain the nipple in engagementtherewith. i

3. The combination with the cylinder of an internal combustion engineand a priming cock therefor, having a priming cup at its outer end, of areceptacle for a cleaning liquid, a valved drainage cock projecting fromsaidreeeptacle a nipple threaded on the outer end of said drainage cockand adapted to project at its outer end into said priming cup,anadjustable stop-shoulder on said nipple for seating on the rim of thepriming cup, an outwardly opening checkvalve in the passage formed bysaid drain cock and nipple, and a catch member piv-.

otally connected to said nipple for transverse swinging movementsrelative thereto and havin its outer end portionshaped to swing un ersaid priming cup "a ndfcoopcrate therewith to retain the nipple" iniclose engagement therewith.

In testimonywhereot, I have hereunto signed my name to thisspecification,

- ARTHUR THOMPSON.
